We're dividing 24572542 by 991 
The aim is to understand the frequency of 991 in 24572542.

Moving on to step 1:
991 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 991

Advancing to step 2:
991 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 991

Going ahead to step 3:
245 divided by 991 is 0 with a remainder of 245.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 245 after subtracting 0 from 245.
Take the next digit (7) from the dividend and append it to 245, then repeat: 2457 / 991

Going ahead to step 4:
When dividing 2457 by 991, we get 2 with a remainder of 475.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1982 from 2457 leaves us with 475.
Append the next digit (2) from the dividend to 475 and continue with: 4752 / 991

Going ahead to step 5:
991 goes into 4752 4 times with a remainder of 788.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 3964 from 4752 and we're left with 788.
Fetch the next digit (5) from the dividend, attach it to 788 and continue: 7885 / 991

Going ahead to step 6:
7885 divided by 991 is 7 with a remainder of 948.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
If we take 6937 away from 7885, we end up with 948.
Append the next digit (4) from the dividend to 948 and continue with: 9484 / 991

On to step 7:
If we divide 9484 by 991, we get 9 and a remainder of 565.
The number 9 becomes the next digit in our result. 
Result so far: 2479.0
If we take 8919 away from 9484, we end up with 565.
Include the next digit (2) from the dividend after 565, then repeat: 5652 / 991

Advancing to step 8:
When dividing 5652 by 991, we get 5 with a remainder of 697.
Put 5 as the next digit of the answer. 
Result so far: 24795.0
Deduct 4955 from 5652 and we're left with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Going ahead to step 9:
The number 991 fits into 6970 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 24795.7
Subtracting 6937 from 6970 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
When dividing 330 by 991, we get 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 24795.7
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 11:
If we divide 3300 by 991, we get 3 and a remainder of 327.
The next digit of our result is 3. 
Result so far: 24795.703
If we take 2973 away from 3300, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 12:
When dividing 3270 by 991, we get 3 with a remainder of 297.
Record the quotient 3 as the next digit in the result. 
Result so far: 24795.7033
If we take 2973 away from 3270, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The final result is 24795.7033 with a remainder of 0.00297.
